Having problems with your PC Desktops ?

My Pavillion a636n hangs at the blue HP Invent screen when trying to boot. The disk access light is on continuously at this stage. Is this liekly to be a problem with the motherboard or something else?

Answers :

Hello!\015\012\015\012Try clear cmos. If you stil have same problem, it is in most case trouble with bios, and that is the end with computer, because you can´t try upgrade bios in DOS, you keyboard isn´t in function.\015\012In some case you have trouble with port for keyboard, try usb keyboard. Or you can have problem with any part of motherboard, who bios need. \015\012Does you hear any beep?

Not certain from here, but I would guess harddrive or disk controller.. Have you tried going into BIOS and setting to boot from CD. Place your OS disk in CD drive and boot from it. Then attempt a repair on OS. \015\012Another thing... you could have the system BIOS search for the harddrive. If it cannot find one, that perhaps is your problem. What do the boot screens tell you? I hope this helps you get a clue what might be happening. Oh, do you get any beeps when the PC first posts? How many?

Laptop will not boot from either hard drive or boot cd - sometimes

Sounds to me like both of you may be having hardware issues. When you try to enter the BIOS, it will poll all connecting ports (IDE, mini-PCI USB Hubs etc) to find out what is attached so it can be manipulated in the BIOS utility (of course HP/Compaq ...

I have an Acer Aspire 7520 laptop. I took off the back plate to clean it and when I put it back on the laptop does not bootup. You turn on the power and the power light comes on, the hard drive access light flikers twice and goes out as does the CDROM access light. The system goes no further. Is it a motherboard issue or something else? Is there a continuity coating on the back of the cover? The copper color on the back of the cover is wearing off.

Hi,Which plate did you take off? the hard drive cover? I would try some basic troubleshooting like uninstalling/reinserting the ram and the hard drive. Then go from there. Also how long have you owned the laptop? What did you clean it with and ...
